*http://support.citrix.com/article/CTX133910

     Gather the UUID’s of the pools you wish to auto-start.
    To get the list of the pool’s on your XenServer type “xe pool-list”
    Copy the UUID of the pool. If you have just one server, it will still have a pool UUID as noted in the following screenshot:

    Then type the following command to set the pool or server to allow auto-start:
    xe pool-param-set uuid=UUID other-config:auto_poweron=true
    Note: *Replacing UUID with the UUID of the XenServer or pool.*

Setting the Virtual Machines to Auto-Start

    Gather the UUID’s of the Virtual Machine you want to auto-start by typing:
    xe vm-list
    Note: This generates a list of Virtual Machines in your pool or server and their associated UUID’s.
    Copy the UUID of the Virtual Machines you want to auto-start, and type the following command for each Virtual Machine to auto-start:
    xe vm-param-set uuid=UUID other-config:auto_poweron=true
    Note: *Replace UUID with the UUID of the Virtual Machine to auto-start.*
